Folks,
I agree to Antonio on the redistribution of connected interfaces, I had
asked this question recently in Networkers 2007 during eigrp session held by
Don Slice and the answer was " it is not necessary for the connected
interfaces to mention the metrics during the redistribution", but for the
other routing protocols redistribution into eigrp it is a must, other wise
you will see routes acting funky in eigrp topology table.Specailly the
feasible successor were disappeared in one particular scenario, I did during
my practice lab, when I removed the metrics from the redistribution of one
routing protocol into eigrp.
Thanks,
Bilal
